Does anyone know this cartoon show from the early 1980s? I'll try and describe it...?

In the early 1980s, say somwhere between 82 and 84, there was an animated show on TV. I remember these few facts from a nebulous young memory:

1. it was set in outer space
2. there were human characters
3. the most salient clue, the people lived and fought on ship resembling a naval battleship which had a powerful power canon on the front of its bow. I'm not totally sure, but I think the ship was either blue or red in color (but don't quote me on that one description point)

this show has haunted my idleling memories since then. i can't remember any titles, locations, or character names, yet the images remain.

So does anyone have a clue or idea to what I'm recalling from the past? Any names or videos on the Net? Wikipedia or YouTube, perhaps???

I think it was star raiders.

Two choices:

Robotech

Star Blazer (I think its this one)

AH...Yes it was the Yamato battleship and the seies was called Starblazers.It had 4 or 5 series and an OVA..It started as a journey to save mother Earth for the radioactivity brought upon by war...Check out the openning at here...http://www.bestanime.com/newAniData/aniI...

Yeah, I think someone already mentioned Robotech and Starblazers.

Those would be the top contenders.

Robotech is one of my fave anime series from the 80's.
